BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No, 379,355, dated March 13, 1888.

Application filed January 4, 1887. Serial No. 223,389. (No model.)

To all whom it may concern.-

Be it known that I, KARL GEORGE BAREIS, of MacFarland, in the county of Dane and the State of WVisconsin, have invented a new and Improved Band-Gutter and Feeder for Thrashing-Machines, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for cutting the bands of sheaves and feeding the loose grain to the thrashing-cylinder of a thrashing-machine.

The invention consists of various parts and details and combinations of the same, as will be fully described hereinafter,and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improvement. Fig. 2 is a longitudinal sectional elevation of the same on the line :0 a: of Fig. 1. Fig. 3 is a side elevation of the same. Fig. 4 is an end elevation of the same, with parts in section.

The thrashing-machineA is provided with the usual thrashing-cylinder, B, mounted on the shaft 13, carrying on one end the gearwheel B, which meshes into the gear-wheel B attached to the shaft 0, mounted in'suitable bearings on the frame D, extending from and secured to one end of the thrashing-machine A. The frame D is of suitable construction, and carries the several devices constituting my improvement.

On the shaft 0 is secured the roller 0 over which passes the endless belt E, which leads the loose grain to thethrashing-cylinder B and passes over the loose rollers F and F, suitably mounted on the frame D. Above the roller F is placed the grooved roller G, which is held in bearings H and adapted to slide up and down between the standards D, erected on the frame D, and each of the bearings H is connected by an adjustable link, I, with the lever I, on the front end-of which is adj ustand also passes over the roller N. The links I I are made adjustable so as to increase ordiminish the space between the feedbar J and the slat belt M and to regulate the space between the rollers F and G. The bearings H are each held in a downward position by a spring, H, resting with one end on the top of the said bearings H, and its other end bearing against the plate H extending from side to side of the frame, and on the top of which press the screws H passing through the horizontal beams D of the frame D. By operating the screws H the tension of the springs H and the consequent pressure of the roller G may be regulated.

The roller K is secured on the shaft K, on one end of which is keyed or splined the sliding gear-wheel K", which meshes into the gear-wheel L secured on the shaft L, carrying the roller L. The gear-wheel K is provided with a collar, K, on which operates the forked lever Kflfulcrumed on the frame D and serving to move the said gear-wheel K into or out of engagement with the said gear-wheel L thereby preventing grain being fed to the cylinder when it is not in motion, as said gears must first mesh in order that the primary belt M of the carrier mechanism may operate. On the other end of the shaft K is placed a pulley, 1?, over which passes an endless belt, Q, which also passes under the pulley G, attached to the shaft G, carrying the grooved roller G, and around the pulley C secured to the shaft 0. The rotation of the latter imparts motion, by means of the said belt Q, to the rollers G and K, and the latter imparts a traveling motion to the slatbelt M by means of the gear-wheels K and L.

A belt-tightening device, R, is connected with the belt Q, so as to take up any slack of said belt caused by the rising of the grooved roller G and its pulley G This tightening device R consists of aroller, S, bearing against the inside surface of the belt Q and mounted to rotate on a stud, s, secured to an arm, T, pivoted on the segmental arm U and connected with the spring T, having one end secured to the said arm T and its otherend to a pin, t, on the said segmental arm U. The latter is provided with an inwardly-projecting lug,U, which fits into any one of a series of corresponding recesses in the plate U secured to the side of the frame D. The plate U swings on the same stud as the arm T.

A series of knives, V, is arranged across the slat belt M, and said knives are secured to the rock-shaft V, extending across the frame D and mounted on each sidein bearings V sliding between guides on the top ofthe side beam of the frame D.

The knives are adjustable on the rock-shaft V toward and from the slatted belt M by means of the clamps c on their upper ends. Each clamp is made in two sections, one section,o,being formedon the'upper part ofa knife and the other part, o beinghinged to the section 1), as shown at o, a set-screw, v", serving to adjust the two sections securely upon the said shaft V. On the rear end of each of the bearings V is held the upright rod V", on which slides one end of the arm V which has its other end secured to the cross-shaft V. On the rod V is a coiled spring, V resting with one end on the said arm V and its other end bears against a nut, V screwed on the upper end of the said rod V. This arrangement holds the knives in a yielding positionin relation to the slat belt M, so that the knives adjust themselves according to the amount of grain on the said belt.

'Each of the bearings V" is provided with an extension, V, having on its upper surface rack-teeth in which mesh the teeth of a pinion, YV, secured to the shaft mounted in suitable standards erected on the side beams of the frame D. The shaft W can be turned by a crank-arm or other suitable means, so as to cause the shaft V and the knives Vto move toward and from the front end of the frame D. A pivoted locking-arm, XV prevents the pin ion W from turning when thrown in gear, as shown in Fig 2. By thusmovably mounting the knives they may be readily adjusted to suit bundles of different lengths.

The operation is as follows: The rotation of the thrashing-cylinder B imparts motion to the endless belt E, the grooved rollers G and K, and the slat belt M, in the direction indicated by the arrows in Fig. 2. The two said belts E and M therefore form what may be generically termed the carrier or carrier mechanism. The sheaves are thrown upon the front end of the slat belt M, which carries them forward and under the knives V, which cut the bands, and the loose grain is then passed by the slat belt M under the feed-bar J and to the grooved roller K,which presses the grain downward and upon the endless belt E, which carries the grain to and under the grooved roller G, which rises and falls according to the amount of grain carried forward by the said belt E. The upward and downward motion of the grooved rollerG imparts an upand-down motion to the feed-bar J, which thus prevents too much grain from passing to the grooved roller K. The passage of the grain is, however, continuous, as the movement of the belt M of the carrier mechanism is not interfered with by the up-and-down' movement of the feed-bar, said bar descending only far enough to lessen the amount of grain passing under it until the choke is relieved. The grain, after leaving the grooved roller G, is carried by the endless belt E to the cylinder B of the thrashing-machine.

It will be seen that when the roller G rises the belt Q will become slack, but the slack is taken up by the roller S, mounted on the arm T,which swings downward, this motion being caused by the action of the spring T on said arm T. The tension of the roller S on the belt Q can be adjusted by means of the pivoted arm U,which can be moved up or down and locked in position by its arm U engaging one of the recesses in the plate U".

lVhen the machine is to be stopped, the operator can stop the movement of the slat belt, and consequently the feed, by throwing the gear-wheel K out of contact with the gearwheel L by means of the forked lever K so that no more grain can pass to the thrashingcylinder when the latter is slacking up its speed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination,with the carrier mechanism, consisting of endless slat belt M and endless belt E, of the vertically-movable feed-bar above the belt M, the vertically-movable feed-roller above the belt and in rear of the feed-bar, and connections between the said feed bar and roller, whereby when the feed-roller is raised the feed-bar will be depressed, substantially as set forth.
